# In this test, the VDIVPS takes 38 cycles to write to register YMM3. The first
# VADDPS does not depend on the VDIVPS (the WAW dependency is eliminated at
# register renaming stage). So the first VADDPS can be executed in parallel to
# the VDIVPS. That VADDPS also writes to register XMM3, and the upper half of
# YMM3 is implicitly cleared. As a consequence, the definition of YMM3 from the
# VDIVPS is killed, and the subsequent VADDPS instructions don't need to wait
# for the VDIVPS to complete.
# The block reciprocal throughput is limited by the VDIVPS reciprocal throughput
# (which is 38 cycles). The sequence of VADDPS can be executed in parallel on
# the FPA unit; their latency is "hidden" by the long latency of the VDIVPS.
